Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

In this activity, young learners will experiment with a basic chemical reaction and observe what happens when gas gets trapped! Activity includes step-by-step instructions, safety notes and more.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

This activity shows learners (with adult supervision) how to make a Glitter Globe, a fabulous toy that shimmers when you shake it.
